X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b26d19e44adfd10b691bf4ffd50ed411c1be9317;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ALSA: compress: Make sure we trigger STOP before closing the stream. Currently we assume that userspace will shut down the compressed stream correctly. However, if userspcae dies (e.g. cplay & ctrl-C) we dont stop the stream before freeing it. This now checks that the stream is stopped before freeing.
